DESTMODULESNAME is functionally similar to KMODDIR.  Unfortunately the
default value of KMODDIR is defined in bsd.own.mk and only used by
kmod.mk and not by kern.post.mk.  So, currently, if you set KMODDIR to
somewhere other than /boot/modules, modules-install still populates
/boot/modules.old with stripped version of modules in /boot/modules,
not with the ones in $KMODDIR.
The reason kern.post.mk does not care about the default value of KMODDIR
is because the Makefile in kernel build directory does not include
bsd.own.mk, which defines KMODDIR.  I have no idea that bsd.own.mk should
not be included by bsd.post.mk or the Makefile in the kernel build directory.

Cheers.
